Extended Data Fig. 1: Results of the subgroup analysis for the primary endpoint (change in HbA1c after 6 months).
Subgroup analyses were performed by fitting linear regression models with tests for interaction between these variables and study groups to the data. All tests were two-sided, and p values were not adjusted for multiple comparisons. Number of patients refers to ‘n (lifestyle intervention)/n (usual care)’ for each subgroup. FU, follow-up; HbA1c, glycated hemoglobin; HL, health literacy; MCS, mental component score; PCS, physical component score; VO2, oxygen consumption. aCombination of the two answers ‘difficult’ (n = 270) and ‘unknown’ (n = 36).
